Abstract
The present invention relates to a kind of check bolt, including head and thread rod part, have step between described head and thread rod part, being provided with to described step periphery inside described thread rod part can be with the perforation of ft connection；It is additionally provided with the inclined hole that many groups communicate with perforation and extend on described thread rod part periphery at described thread rod part internal-internal；Described inclined hole, perforation and described head and thread rod part integrated injection molding.A kind of check bolt of the present invention, can not only effectively prevent from loosening during transport or life-time service, and add fastening performance, add the security reliability of transport, such that it is able to avoid causing security incident, simple and reasonable for structure.
Description
Technical field
The present invention relates to a kind of bolt, be specifically related to a kind of check bolt, belong to technical field of fastening.
Background technology
The use of bolt is extensive, needs in many instances to closely cooperate between bolts and nuts, to prevent bolt looseness.
Such as the bolt on automobile, the most conventional bolt looseness way that solves is one spring washer of addition between bolts and nuts, with
Prevent bolt looseness.Even if but so the most simply reduce the probability of bolt looseness, not the most former for bolt pine
Because solving.
Summary of the invention
It is an object of the invention to the deficiency overcoming prior art to exist, it is provided that a kind of check bolt, can not only be the most anti-
Only loosen, and add fastening performance, add the security reliability of transport, such that it is able to avoid causing security incident.
For reaching above-mentioned purpose, the technical solution used in the present invention is: a kind of check bolt, including head and threaded rod
Portion, has step between described head and thread rod part, is provided with to described step periphery inside described thread rod part
Can be with the perforation of ft connection；It is additionally provided with many groups at described thread rod part internal-internal to communicate and to described screw thread with perforation
The inclined hole extended on bar portion periphery；Described inclined hole, perforation and described head and thread rod part integrated injection molding.
Preferably, described inclined hole is that ratchet-like is connected with described perforation, and described perforation is L-shaped, is in described screw thread
In bar portion, another side is in described step, and extends to step periphery.
Preferably, bottom described thread rod part, it is embedded with card article on periphery.
Preferably, described card article has many groups and circular array.
Due to the utilization of technique scheme, the present invention compared with prior art has the advantage that
A kind of check bolt of the present invention, can not only effectively prevent from loosening during transport or life-time service, and add
Fastening performance, adds the security reliability of transport, such that it is able to avoid causing security incident, simple and reasonable for structure.
Accompanying drawing explanation
Below in conjunction with the accompanying drawings technical solution of the present invention is described further:
Accompanying drawing 1 is the structural representation of a kind of check bolt of the present invention；
Wherein: 1-head；2-thread rod part；3-step；4-bores a hole；5-inclined hole；6-card article.
Detailed description of the invention
Below in conjunction with the accompanying drawings and specific embodiment the present invention is described in further detail.
As shown in Figure 1, a kind of check bolt of the present invention, including head 1 and thread rod part 2, at described head 1
And there is between thread rod part 2 step 3, step 3 can be the movable step with female thread, internal to institute from thread rod part 2
Stating that step 3 periphery is provided with can be with the perforation 4 of ft connection；Inside described thread rod part 2, it is additionally provided with many groups and wears
The inclined hole 5 that hole 4 communicates and extends on described thread rod part 2 periphery；Described inclined hole 5, perforation 4 and described head 1 and screw thread
Bar portion 2 integrated injection molding.Wherein inclined hole 5 is connected with perforation 4 in ratchet-like, and inclined hole direction is downward-sloping, with axial through bore
Between angle be 45 °, perforation is 4 L-shaped, is in described thread rod part 2, and another side is in described step 3, and to
Step 3 periphery extends.The bolt of the present invention produces vibration during life-time service or in transportation time, perforation 4 and tiltedly
The setting in hole 5 is easy to discharge the gas produced because of vibration in screwed hole gap, thus beneficially between screwed hole and screw thread
The acquisition of vacuum between gap, thus increase its fastening performance.
Four groups or six groups and circular array card article 6 it is embedded with on periphery, when the spiral shell of the present invention bottom thread rod part 2
When bolt screws in nut, the screw thread in nut makes card article produce dilatancy, to contacting with thread rod part 2, plays and holds out against pressure again and again
The effect compeled, and make not have between nut and bolt tolerance, increase its coefficient of friction, improve its fastening performance, prevent transport
Or use during produce vibration and cause loosen, security reliability.
Below it is only the concrete exemplary applications of the present invention, protection scope of the present invention is not constituted any limitation.All employings
The technical scheme that equivalents or equivalence are replaced and formed, within the scope of all falling within rights protection of the present invention.
Claims (4)
